Jayalalithaa is alive but her condition is very critical, Apollo Hospitals says, What is  ECMO, meaning of ECMO, Jayalalithaa died

J Jayalalithaa, who suffered a cardiac arrest on Sunday evening, continues to be very critical and is on extracorporeal membrane oxygenation (ECMO) and life support systems, said Apollo Hospitals in a statement on Monday.
"The chief minister is being treated and closely monitored by a team of experts," said the statement issued by Apollo Hospitals chief operating officer Subbiah Viswanathan. A team of doctors from the All India Institute of Medical Sciences would land in Chennai later this afternoon, doctors said.

There was short panic after some Tamil channels and websites published reports of Jayalalithaa's death, which was rubbished by Apollo Hospitals. According to the hospital, the TN chief minister was still under life support though her condition was critical. An emergency meeting of AIADMK party members was also on to discuss a possible successor. The party, according to reports, may back O Panneerselvam, who has been Jayalalithaa's trusted lieutenant.

Jayalalithaa is on ECMO or Extra-Corporeal Membrane Oxygenation device. This is a life support system that helps provide oxygen to the body when the patient's lungs or heart are unable to do so. ECMO is put in place when the patient becomes unresponsive to conventional CPR or Cardiopulmonary resuscitation. It works by draining blood from a vein and connecting it to an oxygenator machine. According to doctors, the patient can be on the device for several days or even weeks.
The state, however, has been put on high alert. Tamil Nadu DGP has ordered all police officers and personnel to be on duty. In a communication to ADGPs of Enforcement, CB-CID, Economic Offences Wing and Crime wings, the DGP's office today asked them to "mobilise all the officers in the rank of SPs and police personnel of other ranks of Enforcement, CBCID, EOW and Crime completely and they should report" to SPs and Commissioners of Police on Monday.
